Hydrogen only has 1 electron.
Four.
Only one valence electron.
HCN, hydrogen cyanide, has a total of 10 valence electrons. Hydrogen contributes 1 valence electron, carbon contributes 4 valence electrons, and nitrogen contributes 5 valence electrons.
Two electrons will fill a hydrogen's outer, or valence, shell.
Hydrogen has only one valence electrons.
Four.
14 total electrons. 5 valence electrons.
There are three valance electrons. These are the electrons in the outer shell if it is not full.
One. A hydrogen atom contains only one electron, and it is a valence electron.
A hydrogen atom has 1 valence electron.
It's called a valence electron, and there's 1 for a hydrogen atom
5
Hydrogen chloride (HCl) has 7 valence electrons. Hydrogen contributes 1 valence electron and chlorine contributes 7 valence electrons.
Only one valence electron.
1
The valence of hydrogen is 1. This means that hydrogen has one valence electron, which allows it to form one covalent bond with other atoms.
Hydrogen doesn't really have a valence shell. It has one electron only.
